Rash on Test*les and itch. Very serious?

Thanks for the query. This presentation can be seen with many skin diseases. The best option is to consult a Dermatologist in person to understand the problem and get it diagnosed. A proper treatment can then be started. Discuss the situation and hope it will be cleared in few days. Don't delay the appointment. You can use a bland moisturiser till then and OTC anti-allergic medications.You need to meet a good Dermatologist to have a proper diagnosis. Can it be psoriasis or something else? Once the diagnosis is ascertained,proper treatment can be initiated. If it's eczema , an attempt to find the triggers has to be made or else it keeps recurring. Don't lose hope and the problem can be cured for sure. Hope it helps. Hope it helps you. Dr MK Agarwala
